Monitoring Metabolic Energy Expenditure via the Prostheses of Lower Extremity Amputees

Project: Research project

Description

Brief summary/abstract draft: The objective of this solicitation was to develop, implement and evaluate rehabilitative technologies that monitor metabolic demands of energy expenditure during varied Activities of Daily Living (ADL) activities in lower extremity amputees. This technology should support soldiers returning to active duty. The objectives for the Phase II program include: (1) refine the Phase I design, to further optimize components of the heart rate sensors, data acquisition microprocessor, and user interface; (2) conduct system usability testing to get patient feedback on comfort level; (3) collect energy expenditure data from subjects while wearing the TEQUILA system and simulateously recording energy expenditure via indirect calorimetry; (4) develop energy expenditure model using polynomial neural networks; (5) collect additional EE data for prospective model validation; (6) analyze data. Tasks 1, 4, and 6 will be conducted by the BAI research team. The Ohio Willow Wood Company (OWWC) will act as a contractor to embed the refined sensors into gel liners for Task 1 and will assist with usability testing in Task 2. Task 3 will be done by the Rehabilitation Technologies& Outcomes Laboratory at the Rehabilitation Institute of Chicago (RIC) with collaborator Dr. Arun Jayaraman; Task 5 will be conducted by ASUs Healthy Lifestyles Research Center with Dr. Glenn Gaesser. Additionally, OWWC will work with the RIC, ASU, and BAI to provide gel liners embedded with TEQUILA sensors and custom fit to participating subjects in Task 3 and 5.
